Water flow monitoring system determining the presence of leaks and stopping flow in water pipes
First Claim
1. In a fluid flow monitoring system for determining the presence of leaks in plumbing pipes of a plumbing pipe system having fluid flowing therethrough under high pressure, the system comprisinga flow monitoring device mounted to a pipe of the plumbing pipe system for sensing the flow of fluid through the pipe, control means to monitor time, flow rate, and accumulated volume measurands received from said flow monitor, said control means comparing current flow rate to prior flow rates during water usage and resetting to zero the time and accumulated volume measurands during continuous flow upon detecting sufficient decrease in flow rate, and action taking means actuated by said control means when continuous said flow exceeds measurand limits.

Abstract
A water flow monitoring system for determining the presence of leaks in plumbing pipes having water flowing through the pipes under high pressure includes a flow monitor which is mounted to the pipe for sensing the flow of water through the pipe. A controller composed of a timer and/or accumulated volume meter associated with the flow monitor, to determine when the flow has continued for a preselected period of time, and/or when the amount of water has exceeded a preselected accumulated volume threshold, and logic components responsive to changes in flow rate. Upon detection of flow for the preselected period of time, and/or preselected accumulated volume threshold, a valve is actuated to stop flow through the pipe.
